Fuel system for 700rwhp 1998 fbody Alright, I am probably going to Lonnies but figured I would ask here first. Since of course my trans am is a 98, I know I need different things. Turbo kit is being installed now, I have everything ready to go but the fuel system. I need Injectors, fuel rail, and pump I assume. What does everyone recommend that will give me a 700rwhp capable fuel setup? I was planning to do 80 injectors, not sure on pump/pumps and fuel rail/lines yet. Or what I need to make this work in a 98 setup.

Check out my build thread in my sig
Single turbo 98 camaro
I used dual walbro 255's, with one coming on under boost via a Hobbs switch.
Nasty performance fuel rails
Siemens deka 80 lb injectors
-8 an feed, -6an return line
This setup is good for 1,200 hp
But 700 you should be able to utilize the stock fuel lines for now.

Yep,
I used dual walbro 255's, with one coming on under boost via a Hobbs switch. Do this. $250~ in the tank is all you need these days for 700rwhp. No sense spending much more than that, the hobbs switch is fundamental to keeping the fuel temp down and conserving the second pump. Might want to cycle them after 6 months though (make the aux pump into the primary for a while to spread the load).

Yea I figure with rails, pump, and injectors either way I look at it I'll be around $1500+ easy. Lonnies is around $2300, 2500 probably with taxes and shipping etc. So I'm debating just pulling the trigger on that and getting it all said and done.

Walbro 450 pump in the stock bucket will cost you less than $200.
Use the stock lines, rails, fittings, etc and Deka 80 lb injectors. Nothing else...
Guys going the 'easy route' and spending 4-5 times what they need to are the reason that so many projects get parted out before they are finished. Roll those sleeves up and save some money.

If you were going to stay at 700... I'd say that's a good idea.
If you plan to push 850+ (which wouldn't be hard) then going with ID1000s, twin DW200s, and the -8AN/-6AN lines + Rails would be a good investment. The 80s won't be enough for that and neither will the 450. So you end up buying things twice... But it would definitely hold you over.

Well I thought I need custom work done to make fit for a 98? 99+ fbodies have no problem doing the pumps, but because I have a different tank I heard it's a lot more work? And a single walbro 450 would handle 700? As well as stock lines?

My range of power is going to be high 600s to low 700s, no more for sure. That being said, I would like to see what everyone is doing who was able to do these pumps on a 98 is the issue im running into.
This will be on pump gas by the way, not e85. So you really think a single 450 with stock lines and 80lb injectors will be enough for my goal? Just wanna make sure I'm reading that right before I go looking for a 450 pump and injectors. Thanks guys.

Just do this, don't over complicate thing and spends tons of money where it isn't needed.

The Lonnie's Double Pump is good to about 700rwhp with the stock lines. It's $625 and works in the 98 tank. That plus the 80s would be good. Then you're ready for more if you ever decide to do more. Just swap to -8AN/-6AN lines, a FPR, and billet rails.

PSI with my 80s, and have since ran 30 PSI.
The walbro 450 has been pushed to around 900whp as well. I don't think ive seen it over that yet. You can get them for $130. Much cheaper than the $600 double pump setup.

FWIW. I have dual 340s in my tank (one on a hobbs) with 8an feed and stock line as return w/stock rails and SD80s. On the dyno made a little over 800hp @64-70% dc. Made my own wiring harness.

Alright so http://walbrofuelpumps.com/walbro-f9...-fuel-pump-e85 for fuel pump. I'll get 80lb bosch injectors, anything else you would suggest for this? Hotwire kit or anything?
